You've got some good musical ideas in your guitar phrasing (great legato)but it would sound even better if you had some interesting variation in the rhythm section backing track, maybe some chord changes over top of the ostinato bass. Maybe add some drum fills to make things more interesting to the listener and to add more dynamics. Sounds like you could boost the overall mix too with a compressor limiter or exciter to give the mix more punch...good effort overall. :)
